Abstract:
We aimed to assess the relationship between subjective sleep quality and occupationally-relevant outcomes in military personnel. Participants were from an elite unit of US Army soldiers who worked extended (~30 h) shifts (with minimal recovery time between shifts) during 3-week work sessions. Questionnaires assessing subjective sleep quality during the month prior (Pittsburgh Sleep Quality Index [PSQI]) were administered at the beginning of the session. Occupational outcomes (emotional exhaustion, functional impairment, role overload, daytime sleepiness) were assessed on the final day of the session. Regression analyses were conducted to link sleep quality and occupational outcomes. The study sample participants had relatively poor sleep prior to the exercise (PSQI Global score average = 6.3 ± 3.1). Higher PSQI Global Scores prior to the work session longitudinally predicted daytime sleepiness (f2: 0.56) after the work session. PSQI component 7, which queries daytime dysfunction attributed to poor sleep quality, longitudinally predicted emotional exhaustion, functional impairment, and role overload (f2 range: 0.19-0.70). In conclusion, poor sleep quality-in aggregation with occupationally-mandated sleep loss-is predictive of poorer subsequent occupational outcomes. Future work should aim to increase sleep opportunities prior to occupationally-mandated sleep loss in order to build resilience when sleep loss is unavoidable.
摘要:
我们旨在评估军事人员主观睡眠质量与职业相关结果之间的关系。参与者来自美国陆军士兵的精锐部队,他们在为期3周的工作会议中工作了长时间(〜30小时)轮班(轮班之间的恢复时间最短)。在会议开始时进行问卷调查,评估前一个月的主观睡眠质量(匹兹堡睡眠质量指数[PSQI])。职业结果(情绪疲惫,功能损害,角色过载,白天嗜睡)在会议的最后一天进行评估。进行回归分析以将睡眠质量和职业结果联系起来。研究样本参与者在运动前睡眠相对较差(PSQI全局得分平均值=6.3±3.1)。工作会议之前较高的PSQI全局分数纵向预测了工作会议之后的白天嗜睡(f2:0.56)。PSQI组件7,查询归因于睡眠质量差的白天功能障碍,纵向预测情绪疲惫,功能损害,和作用过载(f2范围:0.19-0.70)。总之,睡眠质量差-与职业规定的睡眠损失聚集在一起-预示着随后较差的职业结局.未来的工作应旨在在职业规定的睡眠不足之前增加睡眠机会,以便在不可避免的睡眠不足时建立恢复力。
